IMPROVEMENT IN RESPIRING APPARATUS.

Specification forming part of Letters Patent No. 153,194, dated July 21, 1874; application tiled February 27,1874.

expiring air from and into said reservoir.

The apparatus is used to furnish pure air for breathing in all localities where vitiated air, impure gases, smoke, &c., render the atmosphere unlit to sustain life, such as mines, buildings on lire, deep wells, chemical apparatus, diving, Sto.

Sheet No. l ot' drawing shows the apparatus in use.

In Figure l, Sheet 2, A represents an airtight bag, made of a skin or any other air-tight cloth or material. B and C are two india-rubber or other lexible pipes, penetrating to the inside of the air-bag-one fastened near the top, and the other dropping to a point near the bottom. These pipes, after passing to the outside a certain distance, are fastened to the mouth-piece D. D is a mouth-piece, so shaped as to fit inside ofthe mouth, so as to be held by the help oit' the teeth and lips. E are two straps fastened to the air-bag, and by which it is carried by the bearer.

Fig. 2 shows a top view of Fig. Il.

Fig. 3 is an enlarged view of the mouthpiece D, pierced with two holes, and extended into two tubes, around which are fastened thel inspiring and expiring tubes B and C. This mouth-piece has no valves.

Fig. 4. represents a bellows for inflatin g the air-bag, with the mouth-piece D inserted into opening F.

Fig. 6 shows how the straps E are fastened to the airbag. A pulley grooved on the periphery is inserted into an opening made in the air-bag, and the edges of the cloth are brought over the groove, and fastened by wires or strings, Svc.

To use the apparatus I proceed as follows: The air-bag is inflated with the bellows. When full, the tubes B and G are stopped by pressure with the fingers, or by twisting them so as to arrest the escape of air from the bag. The bag is now strapped to the back, the nose stopped with spring-pinchers or otherwise, the mouth-piece is inserted between the lips, and the pipes relieved from pressure.

The apparatus is now ready for breathing. This is accomplished by inspiring air from the pipe C, while with the tongue the opening in B is stopped. The tongue is now shifted over the opening in C, and by so doing the pipe B is left open to expire the air contained in the lungs.

This process of inspiring and expiring air is continued until the air contained in the reservoir is so vitiated by expiration as to become unfit to be breathed any longer.

It will be seen that the air for inspiration is taken from the top of the air-bag, where it mouth-piece D, the air-tubes B and C, one

having its end suspended near the inner upper end of the air-bag, and the other pendent and reaching near the bottom, all substantially as herein described.
